Abstract
Provided is an integrated power station instrument ball valve. The instrument valve is a pipe accessory, leakage in the connection position of a valve body and a valve deck is called as inner leakage and generally called as untight closing, and the capacity of cutting off media by the instrument valve is affected. The integrated power station instrument ball valve comprises a nylon handle (1) connected with a locking nut (2); the locking nut is connected with a pressure ring (3); the pressure ring is connected with a bush (4); the bush is connected with a sealing sleeve (5); the sealing sleeve is connected with a packing box (6); the packing box is connected with a lateral ring (7) and a lateral plate (8); the packing box is connected with a spherical valve rod (9); the spherical valve rod is connected with a panel nut (10) connected with the valve body (11); the valve body is connected with a cutting ferrule nut (12), a front cutting ferrule (13) and a rear cutting ferrule (14). The integrated power station instrument ball valve is mainly applied to controlling conveying media to flow.
Description
technical field:
the present invention relates to a kind of body formula power station gauge ball valve.
background technique:
instrument valve is a kind of pipeline fittings, and it is used to change path section and media flow direction, controls a kind of device of fed sheet of a media flowing.The sealability of instrument valve refers to that each sealed department steric hindrance of instrument valve stops the ability of dielectric leakage, it is the most important technical performance index of instrument valve, the leakage of the joint of valve body and valve gap is called interior leakage, namely usually saidly to fit badly, it blocks the ability of medium by affecting instrument valve, for block valve class, interior leakage is unallowed.The leakage at rear two places is called and leaks outside, and namely medium is from valve internal leakage to valve.Leak outside and can cause loss of material, befouling environment, also can cause the accident time serious, for inflammable and explosive, poisonous or have the medium of radiation, leak outside unallowable especially, thus instrument valve must have reliable sealability.
summary of the invention:
the object of this invention is to provide a kind of integral type power station Gauge Valves.
above-mentioned object is realized by following technological scheme:
integral type power station gauge ball valve, its composition comprises: nylon handle, described nylon handle is connected with locking nut, described locking nut is connected with pressure ring, described pressure ring is connected with lining, described lining is connected with stuffing box gland, described stuffing box gland is connected with stuffing box, described stuffing box is connected with side ring, side panel respectively, described stuffing box is connected with spherical valve rod, described spherical valve rod is connected with panel nut, and described panel nut is connected with valve body, and described valve body is connected with cutting ferrule nut, front cutting ferrule, rear cutting ferrule respectively.
described integral type power station gauge ball valve, described stuffing box column-shape showering has vertically got through four circular columns faces mutually.
described integral type power station gauge ball valve, described spherical valve rod is vertically mounted in valve body, and described stuffing box is enclosed within described spherical valve rod.
described integral type power station gauge ball valve, described valve body is the rectilinear valve body of threeway.
described integral type power station gauge ball valve, described cutting ferrule nut and the Placement of valve body are that double card is overlapped and is connected.
described integral type power station gauge ball valve, described lining and described stuffing box adopt teflon to be material respectively, and described cutting ferrule is ionic hardening cutting ferrule.
described integral type power station Gauge Valves, described valve body can connect metric system, stainless steel seamless pipe made in Great Britain.
beneficial effect:
1. the present invention only needs nylon handle to rotate 90 ° in the ordinary course of things and just completes standard-sized sheet or complete shut-down action, is easy to realize fast opening and closing.Can realize fast opening and closing, the opening and closing time of some structure is only 0.05 ~ 0.1s to guarantee in the automatic system for test stand, and during fast opening/closing valve, operation is without impacting.
2. lining of the present invention and stuffing box adopt tetrafluoroethylene to be material, there is certain elasticity, when the sealing pair that metal and nonmetallic material form, be commonly referred to soft seal, the sealing of soft seal easily ensures, and to the machining accuracy of sealing surfaces and surface roughness requirements also not bery high, there is good self lubricity, little with the fretting wear of valve body, and due to the improvement of the processing of sphere technique, roughness is reduced, thus improves the working life of ball valve.
3. the present invention is when standard-sized sheet and full cut-off, and the sealing surface of spheroid and valve seat and medium are isolated, and therefore can not be caused at a high speed the erosion of sealing surface by the medium of valve
4. compact structure of the present invention, lightweight, can think it time for the most rational valve mechanism of cryogenic media system, valve body is symmetrical, welds valve body structure, can bear the stress from pipeline well time especially.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present invention.
